Landau-Zener effect, superfluid model, cluster-decayThe Landau–Zener effect is generalized for many-body systems with pairing residual interactions. The microscopic equations of motion are obtained and the 14C decay of 223Ra spectroscopic factors are deduced. An asymmetric nuclear shape parametrization ...

Tunneling Josephson effect Bose-Einstein condensates in periodic potentials solitons vortices and topological excitationsWe study stationary and dynamical properties of the many-body Landau-Zener dynamics of a Bose quantum fluid confined in two coupled one-dimensional chains, using a many-body ...
The effect of the small MQ interaction \(\delta \ll {E}_{m},\omega \) can then be taken into account perturbatively. To the first-order perturbation approximation which involves a 2 × 2 Floquet matrix, we obtain a LZS oscillation in occupation probabilities \(|{\psi }_{0}(t{...
In a recent experiment31, degenerate superconducting states with even- and odd-number of electrons in a nanowire topological superconductor of mesoscopic size have been revealed in terms of the Coulomb blockade effect32,33. This experimental breakthrough motivates us to seek for the possibility of ...
Whereas the kinetic energy and the current carried by the electrons show dynamical localization in the nondissipative case, this quantum-interference effect is destroyed and replaced by the relaxation into a periodic limit cycle, if the coupling to a heat bath of phonons is switched on. The ...
the crossing rate of the energy levels. In the subcritical regime, the transition probability still follows an exponential law but with the exponent changed by the nonlinear effect. For $C/V>>1$, we find a near unit probability for the transition between the adiabatic levels for all values ...
Based on our description of the weak measurement, we simulate a system with up to n=200 nuclear spins per dot and qualitatively explain recent experimental findings. Scaling in n indicates a stronger effect for larger n, also in qualitative agreement with experiments. 展开 ...
The SS theory takes into account the dephasing effect due to stochastic field fluctuations. Combining this theory with measurements of dephasing times for MM could lead to a revision in tunnel splitting calculations. But, as far as we know, there are no estimates for dephasing time of MM. The...
Extremely accurate interferometric signals generation by means of geometric phase effect has been demonstrated in this work with the goal of realizing robust control of the quantum coherent states of the polaritonic system. This geometric phase enhancement, which is essentially originated from the dynamic...
